Phase 1Three packs of 2 dragons and 2 melee adds spawn on a 1min timer (i think). Additionally, there are sappers on a different timer which need to die quickly, and gariona casts her twilight onslaught. This phase is very messy in general because there's loads going on. It requires good situational awareness from all players as well as good communication, and a little luck. Let's look at the different aspects:

Drakes: They need to die the first time they are pulled to the ship. Both hunters with CDs and warlock dots killed one, the casters (warlock main nuked it too) killed the other. In the last wave, one drake is killed in the second pull, because the melee adds need to be dealt with first. It is possible for melees to hit them too if they stand on the very edge of the ship, but it's a bit tricky.

Melee adds: Whenever possible, they were tanked on top of a drake, and always close to each other. The rogue stays on them all the time, killing the one that does the cone AE effect first. Once the drakes are down, the casters switch and finish them off. In the last wave, one melee add should die before the second drake because the transition starts as soon as both drakes are down.

Sappers: To force them out of vanish, make sure to spread AoE effects in front of the cloud as best as possible. The hunter's flare works fine too. Stun and slow them as soon as they are visible, it is best to assign someone this job (WL in our case). If a tank is free, he should focus on stopping them. Kill them quickly.

Twilight Onslaught: Everyone should always stand in them. Use defensive individual and raid cooldowns, be careful to turn the melee adds away from the grou.

Twilight barrage: You'll need to take about 8 of them, depending on how fast you are. The faster the drakes die, the less will spawn. Make sure that at least two people stand in them unless defensive cooldowns are used. This can be tricky due to latency; efficient voice communication is absolutely mandatory.

The main difficulty here is that everything happens at the same time, like drakes (which need to die quickly) plus sapper plus Twilight Onslaught at the far end of the ship, while there's fire everywhere. If you get all these things right, it all depends on how lucky you are with fire. If it is all over the ship when phase 2 starts, you might get into trouble.

Phase 2This part is a dps and heal race, the enrage timer starts once Blackhorn lands. The melees should get him as low as possible, while the ranged dps the dragon to ~85%. That will force him into landing; at this point, all DPS switches to Goriona to take her to 20%. They are tanked on top of each other, but look in different directions (~45° apart), so that the breath hits one tank only. Tanks need to swap targets every now and then to reset the debuff. The group stacks up at 10y range to avoid the silence and have short distances when avoiding the shockwave at the same time. The consuming shroud debuff is best healed through slowly and will stop appearing once Goriona flees. It might be helpful if a healer stands away from the AE effect to avoid pushback.Once there's blackhorn only, the group can spread a bit. Now, it all depends on how well the tanks can be kept alive, and how fast the DPS can take him down. Be sure to not stand too far away from Blackhorn, or you might not get out of shockwave in time.
